illegal start of expression ??

[Sonu Shawnee]

What wring with this code,

  /**
   * Checks to see if the variables have been initialized.
   *
   * @return <CODE>true</CODE> if the variable have been initialized,
   *         <CODE>false</CODE> otherwise
   */
  public boolean isInitialized() {
    if(!initialized) {
      initialized = (questionArray.capacity() == NUMBER_OF_QUESTIONS &&
     for(int i = 0; i < NUMBER_OF_QUESTIONS; i++)
     questionArray.elementAt(i) != null);
    }
    return initialized;
  }

thats making it cough these errors ??

RANData.java:117: illegal start of expression
                     for(int i = 0; i < NUMBER_OF_QUESTIONS; i++)
                     ^
RANData.java:118: ')' expected
                        questionArray.elementAt(i) != null);
                                                           ^

Try this, hope it helps !

  /**
   * Checks to see if the variables have been initialized.
   *
   * @return <CODE>true</CODE> if the variable have been initialized,
   *         <CODE>false</CODE> otherwise
   */
  public boolean isInitialized() {
    if(!initialized) {
      initialized = (questionArray.capacity() == NUMBER_OF_QUESTIONS )&&
     for(int i = 0; i < NUMBER_OF_QUESTIONS; i++)
     questionArray.elementAt(i) != null;
    }
    return initialized;
  }

please let me know if that helped .

That helped a bit I guess as now its just one error instead of two.

RANData.java:117: illegal start of expression
                     for(int i = 0; i < NUMBER_OF_QUESTIONS; i++)
                     ^
1 error

Thanks.

Thanks.

Well , Sonu , the reason for that is that you cannot have a for loop as one of the operands of a && operator ....which is what you have done in your case .The logicals operator can be used to test if either of the operands are true or false , that is to test boolean conditions .
the operands can be expressions which evaluate to true or false , but cannot be a for loop !!

got it !!
Yeah, I realized that and so I put the code this way !!

  /**
   * Checks to see if the variables have been initialized.
   *
   * @return <CODE>true</CODE> if the variable have been initialized,
   *         <CODE>false</CODE> otherwise
   */
  public boolean isInitialized() {
    boolean status = false;
      for(int i = 0; i < NUMBER_OF_QUESTIONS; i++) {
        if (questionArray.elementAt(i) != null)
  status = true ;
      }
    if(!initialized) {
      initialized = (questionArray.capacity() == NUMBER_OF_QUESTIONS) && (!status);
    }
    return initialized;
  }

That solved the problem !!
Thanks a bunch !!

Hey Sonu , that looks much better . I'm glad i could be of help .

You could also replace

if (questionArray.elementAt(i) != null)  status = true ;

by

status |= questionArray.elementAt(i) != null;

which is the short form of

status = status | questionArray.elementAt(i) != null;
